I have a product, www.trailervalet.com, that I'm looking to promote. Most of our audience isn't as tech savvy so they're not as easy to find online. Looking for some new ideas to help spurt growth :)
with a product like this, I believe you need to be in a location and position to show the product to consumers. Have you exhibited at The outdoor show, or Boat Show.
This would be ideal for yacht clubs that move boats on trails at start and end of season? Setting a booth or display at local yacht clubs could help get interest and word of mouth.
Physical products often have an Aha! Moment (moment when user get to know the real value of the product) when they first get to use it. Organize test shows, or free trials...anything to get the product working in front of potential customers.
I like all the answers you have gotten so far. My only other recommendation, is when you do a one-on-one demonstration to someone, select a location that other potential clients may be. For instance, if want to illustrate it to one person (could even be a plant - someone you already know) - meet them at the marina on a heavy-traffic day (or yatch club). Then when you are demonstrating it to one person, others will overlook.
